Moisturizing Gel Heel Sleeves help transform rough, dry, cracked heels to be more soft, supple, and healthy. One moisturizing M-Gel zone is located directly over each heel to slowly release medical-grade mineral oil that helps moisturize and rejuvenate damaged skin. Just slip on these comfortable heel sleeves and wear them at rest, work, or play. For best results, wear your gel heel sleeves while sleeping every night for one week. Then wear them for a minimum of 2-3 times per week, or as needed. May be used alone or with a moisturizer cream of your choice for a more intense hydrating treatment.
